What is the mass of the earth?

The mass of the Earth is approximately 5.97 x 10^24 kilograms. It is the fifth largest planet in the solar system and has a density of 5.51 grams per cubic centimeter. The mass of the Earth is important because it determines the strength of its gravitational pull, which keeps objects and atmosphere in orbit and protects the planet from harmful radiation. The mass of the Earth is constantly changing due to the accumulation of dust, meteorites, and other space debris, but its overall mass is relatively stable.
